HSP Diesel Cold Side Tube for 2017-2019 L5P Duramax Trucks

The 605-HSP is your go-to solution when it comes to upgrading the cold side tube for your 2017-2019 L5P Duramax-equipped Chevrolet and GMC trucks. Whether your truck is stock or modified, this upgrade is a smart choice. By replacing a common failure point, you can enjoy peace of mind with this easy-to-install enhancement.

Why Consider the HSP Diesel Cold Side Tube?

The factory cold side tube in the L5P can be a weak link. While it might seem minor, swapping it out can make a significant difference in your truck's performance. The original plastic design is prone to failure without any warning, so making this change is definitely worth your time.

What Sets the HSP Diesel Cold Side Tube Apart?

The factory cold side is made of two pieces of plastic, which not only makes it weak but also creates multiple points of potential failure. In contrast, the HSP Diesel L5P Cold Side Pipe is crafted from durable mandrel-bent aluminum. It features a metal adapter and high-strength silicone boots for installation, effectively eliminating those failure points and keeping you on the road. Plus, you can install it using all factory components without needing any tuning, making the process straightforward and worry-free. With various powder coat options available, you can tidy up your engine bay while boosting your truck's reliability!
